This invention relates to an improved date setting device to be'usedin ticket-issuingmachines, cash registers, and other devices wherein it is desired to "print the date of a transaction.

.lHeretofore' the date printing wheels have been set by manually rotating each one of thewheels' rotated separately the hand of the operator will probably overlap two of, the printing wheels,

16 rotating both of them when he desired to rotate only one. The day printing wheels are generally made as two separate parts, one of which contains the numerals to 9 inclusive and the other the numerals 1 to 3 inclusive. The month print- :ZQ, ing wheel has also been made as a separate wheel. I do not propose to change this arrangement for to do so would require very large wheels which is not desirable. I do seek, however, to overcome the objection of rotating any of the 26, printing wheels which should not be adjusted to "change'the date from, for instance, the 3rd to the 4th.

My invention also relates to means to visually indicate on the outside of the machine what is the setting of the printing wheels on the inside of the machine. In setting the printing wheels the operator need only observe the visual indicator on the outside of the machine which instantly shows the date that the printing wheels are then set to print,

" Obviously many changes may be made in the specific embodiment shown herein by way of illustration without departing from the spirit of the invention. '1, therefore, intend in the attached drawing and the detailed specification to illustrate only the preferred embodiment of the invention, reserving to myself the right to make changes and modifications which may fairly fall within the spirit of the inventive idea and within thebroad terms of the claims at the end of the specification.

In the drawing: Fig. 1 is a side elevational view, Fig. 2 is a plan view partly in cross section, Fig. 3 is a cross-sectional view on the line 3-3 of Fig. 2 looking in the direction of the arrows,

ea in re. Particularly. 9 e evise.

the frame 1 of the machineis provided with a numberof cross bars 2, of which only one, is shown in the drawing, and a secondary frame? is secured tovthe cross bars 2. A shaft; is'ro' tatablyi mounted'in the frame members land 3, 00, which shaft 4 isprovided at its outer end with a substantially rectangular aperture 5 adapted tof receivethe end 6 oi the key 7. The key 7 per-j forms two functions. First, it is a printing key having type 3 which key is'inserted within. the' 8 5,. opening 9'in' the frameljsothat the type 8 willf be in alignment with the printing wheels hereinafter'described, and secondly, it may bare} moved from the opening} and inserted in the opening 5and thereby serveas a meansto tum the shaft 4. The" shaft .4 carrie's a collar w se cured thereto by means ofla pin 11, which collar. carries aten-toothed gear12, which meshes with and drives a iotoothed clear 13, which ear 13 is. provided with'a disk 14 having the daysjof the 15 month from 1 to 31 inclusive thereon as is shown in Fig. 1. The gear 13 is provided with arear' wardly extending tapering hub, 15. The hub 15. receives a sleeve 16 mounted on a shaft 1'? secured.

to the framell. Thesl'eeve 16 carries a disk 181' 50 on which the months are inscribed, as is shown inFig. '1, and also carries a gear 19 which meshes with an idler gear 20p'rotatably mounted on the frame 1, which gear 20 is actuatedby means hereinafter'tol be described. 5 The shaft 4 carries a'sleeve 21 secured thereto by means of a pin 22, which sleeve 21 carries a ten-toothed, gear 23 and a one-toothed disk 24 The gear 23 meshes with a ten toothed gear 25', rotatably mountedon ashaft 26. The gear 25 carries a printing disk 2'7 having numerals 0 to 9 inclusive on itsperiphery. The printingdisk 27 is the disk which prints the units of the days, for instance, the '7 of 27. The one-toothed disk 24 drives a swissgear 28 which swiss gear has se- 5 cured thereto a tens printing wheel 29 and a Gen'evadisk 30 having as many teeth thereon as there are sets of indications on the wheel 29;, The tens printing wheel 29 isprovidedwith' two I or three sets of characters, being; blank 1, 2, 3. 10 The Geneva disk 30 drives a swiss'lgear 31which is integral with 'a toothed gear 32 whichjmeshes withand drives a toothed gea r'33 gon the shait'26,, which gear 33,is secured tofthe months; printing wheel 34. The year pri'nting wheel 35 "is manu- 5 ally operated and forms no part of'this invention. The gears 23 andi32 are 'held inadjusted posi} tion by means of a holding arm 36 'in the form of a lever 37 pivoted on the shaft2 and tensioned by' means or a 'sp'r'nigsc." The 'SWiJsSJEQar 2on no also held in set position by means of an arm 39 pivoted on the shaft 2 and having a depending portion similar to the part 37.

The toothed gear 32 is rigidly secured to a sleeve 40 which carries a toothed gear 41 which meshes with and drivesthe gear 20.

In operation, let us assume that the parts are in the position shown in Fig. 1; that is, the printing disks 27, 29 and 34 are set to print Oct. 13 and the visual disks 14 and 18 show the same date, it being understood that the date to read on the disks 14 and 18 is on the horizontal line extending to the right from the center of same. The date may be changed to Oct. .14 by inserting the key '7 in the aperture 5-and rotating the same clockwise, until the 14 has been brought into the position in alignment with the'word Oct. This, of course, is accomplished directly through the gears 12 and 13, at the same time, however, the gear 23 has been rotated one tooth so that the'units printing wheel'27 is simultaneously set with the disk 14. Each day this simple operation is repeated. On changing from 19 to 20, or from 9to 10, or 29 to 30, it is necessary to rotate the tens printing disk 29 one step which is accomplished by means of the one-toothed disk 24 engaging the swiss gear 28. This is an ordinary transfer mechanism and requires no particular description. Hereinafter the printing wheels 2'? and 29 are referred to as the date printing wheels and the disk 14 as the indicating disk, in contradistinction to the month printing wheel and indicating disk. After the disk 14 has been rotated until the days of that month have been past, the key 7 is rotated until the number 1 appears in correct position. If the month, for instance, were January, which has 31 days, it would be necessary to rotate the key 7 nine spaces in order to set the mechanism for February 1. A To change from February to March would require a rotation of twelve spaces, being the difference between 40 and 28, the gear 13 having 40 teeth thereon. While this is taking place the gear 23 is constantly rotating the gear 25 and the one- "toothed disk 24. When the printing wheels 27 and 29 indicate the number 39 a further rotation will actuate the month printing wheel 34 through the one-toothed disk 24, swiss gear 28 and toothed disk 30, driving the swiss gear 31, the toothed gear 32, and the toothed gear 33, rotating the printing disk 34 one-twelfth of a revolution or the distance between two successive months. While at the same time the gear 32 has rotated the sleeve 40, gears 41, 20 and 19, thereby rotating the disk 14 one-twelfth of a revolution. The reason that a plurality of teeth are placed on the disk is that there are a plurality (2 or 3) sets of numbers 0 to 3 inclusive on the tens printing wheel 29. Such a construction avoids the necessity of continuing to rotate the mechanism until the tens printing wheel 29 had been rotated to 9, as would be necessary if the disk 30 were provided with a single tooth.

It is, therefore, obvious that by my improved structure the mechanism moves synchronously so so that the printing mechanism cannot rotate these .wheels and thereby destroy the correct setting of the same.

Having now described the preferred embodiment of my invention I claim:
